Specification of Letters Patent.

Patented May 8, 1906.-

' Original application filed May 20, 1904, Serial No. 208,987. Dividedand this application filed June 17, 1905. Serial No- 265,676.

To all whom it. may concern:

Be it known that I, DENIS FLANAGAN, works manager, a subject of the Kingof Great Britain and Ireland, and a resident of Clayton-le-Moors, in thecounty of Lancaster, England, (whose post-office address is 26 Oswaldstreet, Claytori-le-Moors,) have invented certain new and usefulImprovements in Cloth-Feeding Mechanism for Sewing-Machines, of whichthe following is a specification.

This invention relates principally to improvements in two-reelsewing-machines, and particularly to an improved cloth-feeding mechanismand to means for indicating the number of stitches per inch being putinto the cloth.

Figure 1 is a longitudinal section of the machine, showing principallythe feeding mechanism. Fig. 2 shows an elevation, partly in section,from the driving end of the machine. Fig. 3 is a plan of the undermechanism of the machine, showing principally the reel-case, loopingdevice, and feeder-motion. Fig. lis an elevation, partly in section,from the right-hand end of Fig. 1; Fig. 5, plan of same.

Referring to improvements in the mechanism for feeding the fabricforward beneath the needle, which is clearly indicated in Figs. 1 to .5,the boss of the disk Z, carrying the looper l, is turned eccentric. Onthe eccentrio is mounted a sleeve 0, having projecting from it two. arms0, designed to receive a shaft 0", which is securely mounted in them,one of said arms having fixed to it the serrated feeder-plate 0', whichpasses through the usual slots formed in the cloth-plate beneath theneedle-bar. The shaft has loosely mounted on it a small ball 1), capableof moving longitudinally of the shaft, and in conjunction with the ballis employed a lever p, pivoted at p to the under side of the bedplate aand provided at its inner end with a spherical bearing adapted toembrace the ball. The opposite end of the pivoted lever is provided witha steel pin g, which may or may not have mounted on it anantlfrlctlonroller. The pin or the roller engages with a cam-groove q,cut in a disk q loosely mounted on a pin at the under side of thebed-plate a. The disk is capable of being moved round its pin 9', so asto vary the position of the pivoted lever, as indicated by broken linesin Fig. 4, and consequently to move the slidable ball nearer to orfarther from the center of the shaft Z, so that the traverse of thefeeder-plate 0' can be altered as designed in accordance with the numberof stitches per inch required to be put into the cloth. The disk ispreferably moved to effect this by means of a small pin 1 or leverprojecting toward the top side of the bed-plate of the machine andpreferably through a slot r, Fig. 1. The pin or lever can be readilymoved to a suitable position, and by the employment of a graduated scale1" at the edges of the slot or by the use of a separate graduated platethe number of stitches per inch to be put in the fabric, correspondingwith the position of the pin, can be seen at a glance. The feedershaft Zis operated by a crank-disk m from the usual top shaft of the machine.

In conclusion, I would have it understood that the feeder-platemechanism may be employed in sewing-machines in which a shuttle is usedfor the bottom or under thread.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a cloth-feeding device for two-reel or other sewing-machineshaving a rotatable shaft, an eccentric mounted on the shaft, aneccentric-ring on the eccentric, arms carried by the eccentric-ring, apin mounted between the arms, a lever having slidable connection withthe pin, whereby movement of the armsis limited, means for adjusting thelever, and a feed member carried by one of the arms.

2. In a feeding device for sewing-machines, a shaft, an eccentricthereon, an eccentricring on the eccentric, arms projecting from theeccentric-ring, a pin carried between the arms, a lever slidablyconnected to the pin, a pin carried by the lever, a disk having acamslot in which the pin is situated, to adjust the lever, and a feedmember carried by one of the arms.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.

DENIS FLANAGAN.
